2005 f-150fx4 5.4l
Hello to all I'm wanting to get some help so here it goes.
I have a 2005 F-150 5.4L FX4 . I have replaced many parts. I bought a scanner and the problems that it read were P0174,P0300,P305,P307, Now I have replaced the O2 Sensors on it the Fuel filter the oil. the truck is running a whole lot better. But the original problem is still there I also replaced the paper filter to a K&N Air filter. Now im still getting same codes. I just bought 4 Coilpacks for the vehicle and thinking of buying the spark plugs. Now many , many individuals have told me changing the plugs is a whole new problem. I also think that my maf sensor is going bad but that code is no longer showing so I think by changing my O2 sensors and the fuel filter fix that problem. Now here are the symptoms that the truck is having. It idles great when I'm Parked once I go up on a steep slope the truck will misfire on me around 50mph and about 2500 rpms. the other misfire that iam having is around 60-70 mph. Sometimes my scanner will pick up P0303 put not always. Please advise on what I can due to narrow down the problem. Before i end up throwing more and more money to the truck that i dont need too My truck has 172k on it.
